' T 0 all whom it may concern:

Be itknown that I, GUs'rAvn J. MARTEL, a citizen of the United States, residing at Chicage, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Tire-Patching Deviccs, of which the following is a specification.

My invention relates to blow-out patching devices for pneumatic tires and has for its object the production of a tire attachment of this character which will be adapted for ready attachment to or detachment from a tire, and whiclrwill be adapted when attached to eli'ectually serve to reinforce the tire at the pointof rupture.

A further object is the provision of a tire patch rhich will be of durable and econoiniv cal construction and eiiicient in operation. Other objects will appear hereinafter. lVith these objects in view my invention consists in a tire patching device characterized as above mentioned and in certain details of construction and arrangement of parts all as will be hereinafter fully described and more particularly pointed out in the appended claims.

'My invention'will be more readily understood by reference to the accompanying drawings forming a part of this specification, and in which,

' Figure 1 is atransverse section of a rim and a pneumatic tire mounted thereon to which is applied a blow-out patching device embodying the preferred form of my inyention, a portion of the patching device being shown in section, Fig. 2 is a. top plan view of a fragment of the tire bearing the patching device, Figs. 3 and 41: are respectively elevations of the outer and inner sides thereof,.and Fig. 5 is an enlarged central transverse section of a portion of the construction shown in Fig. 4, the same being taken on substantially line w en of said figure.

Referring now to the drawings, 1 indicates the rim of an ordinary pneumatic vehicle wheel and 2 the tire mounted thereon.

Said tire consists, as indicated, of an inner air tube 3 and a tire casing t, the latter being prowded ll-11S longitudinal edges with attaching beads 5 which are engaged by corresponding inwardly extending gripping pivotally connected at their inner ends by a pin 9 forming a knuckle joint between the same. The outer ends of said arms are flared or diver-gently formed and are so designed as to adapt the same for snug eugagement or to embrace the peripheral edges of the rim 1 upon which the same may be securely clamped through the medium of a bolt 10, the latter extending through aliuing perforations in said arms and a nut 11 threaded upon said bolt. 12 indicating a lock nut. The arm '7 which is positioned at the outer side of the tire is formed at its outer end with an extension 13. lhc inner side of said extension is. il'ormed with a trans versely extend ng shallow recess let in which is seated a snugly fitting elongate metallic plate 15 which is adapted torest against the tire casing, the inner side of said plate being of a conformation corresponding with that of said casing. Said plate is adapted to be forced into close engagement with the tire casing by means of a: set-screw 16 which is threaded into the arm 7 at a substantially central point therein.

17 indicates lock nuts threaded upon the screw 16 through the medium of which the latter and hence the plate 1 3 may be held in any position of adjustment. The outer edges of said plate at the extremities thereof are. as shown in. Fig. 3, preferably rounded so that in the event of a sudden deflection of the tire the car or vehicle will not be subjected to excessive jarringbecause of the contacting of said extremities of said plate with. the ground. a The plate 15 itwill be observed is adapted for positioning over the zone in the tire in which blow-outs, as is known by those familiar with tires of this character, invariably occur. lVith this arrangement, a blow-out or rupture in'the tire in this locality may be cov red by the plate 15, the latter, through the medium of the screw 16 being adapted to be forced tightly against the tire, as clearly shown in Fig. 1.

At the upper extremity of the member 7 at the inner side thereof is provided a transversely extending recess-18 of a substantially lteylmle form in cross section.

' l9 imlirates a patching band which is formed of any durable flexible material such as leather, fiber or textile. The end 20 of said band is' buckled and is inserted into said recess, the same being securely held therein by means of a pin 21 which extends through the loop in said band. With this arrangement it will be seen that drawing upon said band effects the wcdging of the pin 21 into the contracted outer end portion of the recess 18 and consequently the firm securing of said end of the band therein. With this construction the greater the pull upon said band the more firm will be the gripping of the end 20 thereof in the recess 18. llhe opposite end 20 of said band is rigidly secured in a clamp device consisting of an angular body plate and a movable jawforming plate 24-, the latter being ustably secured to said body plate by means of thumb-screws which pass through the member 2% and are threaded into the member 23. The outer ends 27 of said members 23 and 24 are formed to constitute gripping jaws between which maybe clamped the end 22 of the patching band, In order to insure'a firm lockingof the hand between said jaws the end thereof is looped around a removable pin 28 which is held between said jaws, said pin, as will be observed, sewing-in the same capacity as the pin 21 before described.

In the angular base portion 29 of the member 23 is centrally threaded the upper end portion of av screw 30, the lower endof the latter being in swireied connection with the upper end of a swivel 31. The lower end of. the latter, which is formed into an eye engages a slot'33 formed substantially centrally in the upper edge of the clamp arm 8, the same being swingingly secured to the latter by means of a pin 34 extending transversely through said arm and through the eye The screw 30 adjacent its lower extremity is formed with a squared portion 35 whereby the same may be readily turned by a wrench. with the arrangement disclosed and. with the extremity of the patching band secured as indicatcd it will be seen that in order to effect the tightening of the band about the tire it is only necessary to positively rotate the screw 30, and to loosen the same to rotate said screw in an opposite direction.

\Vith a patching dcvice of a construction as forth then it will be observed that through the plate 15 provision is made for a positive reinforcement of the tire in the immediate vicinity of the blow-out, and that, through the patching band 19 rein forcement of the entire circumference of the tire in the locality of the rupture is effected. quickly attached or detached, the same is of strong, durable and economical. construction and is of highest etlicicncy in operation.

While I have shown what 1 deem to be the preferable form. of my device I do not wish to be limited thereto as there might be various changes made in the details of construcconn'ected clamping arms a The device may be readily andarms adapted to clampingly embrace sai.

rim, a plate adapted for arrangement against the exterior surface of said tire, one of said arms engaging said plate for securely hold ing the same in position upon said tire, and means insaid arm for forcing said plate into close engagement with said tire, substantially as described.

3. The combination with a pneumatic tire and a rim, of a tire patching device comprising two pivotally connected clamping arms adapted to clampingly embrace said rim, means for forcing said arms into clamping engagement with said rim, a plate adapted for arrangement against the exterior surface of said tire adjacent said rim, one of said armsengaging said plate for holding the same in position upon said tire, means in said arm for forcing said plate into close engagement with said tire, and a flexible band adapted to extendaronnd the outer portion of said tire, the respective ends of said band being connected with the outer ends of said arms, substantially as described,

4. The combination with a rim and a pneumatic tire mounted thereon, of a tire patching device comprisin' two pivotally dapted to clamp ingly embrace said rim, means for forcing said arms into clamping engagement with said rim, a plate adapted for arrangement against the exterior surface of said tire, one of said arms engaging said plate for holding the same in position upon said tire, means for forcing said plate into close engagement with said tire, a flexible band adapted to encircle said tire, and means connecting the respective ends of said band to the outer ends ofsaid arms for tightening said band around said tire after the clamp is'secured in position, substantially as described.
